Limit Summons

[Setharoth114]

I'm in the process of making a map and I ran into a snag. I'm using a Troll Witchdoctor that can summon wards, such as a healing ward. However, each Troll Witchdoctor can only summon 1 ward. How do I make this happen? I want it so that the Troll Witchdoctor can only place down 1 ward and when they try to place another one, the old one dies. I would have multiple Witchdoctors on a map. Thanks.

you could use the custom value of a unit. Just set the custom value for the troll that casts it to 1, and cancel the spell if it already has the value of one. When the spell wears off, or the thing dies, set it back to 0

 

[Setharoth114]

that won't work, I'm already using the custom value for something else.

 

[Setharoth114]

hm, would it work if I gave the witchdoctor an inventory, then gave it an undroppable unusable item, then if it placed a ward I could take the item away. Hmmm.... only, I don't know if I could detect who casted the ward if I had multiple witchdoctors...

Er, how many witch doctors can a player owns?

 

[Setharoth114]

Um.... 22 maximum?

Solution = Hashtables!

Instead of custom value, just use an integer. Hashtables will allow you to link the integer to the unit.

 

[Setharoth114]

? How do I use the hashtable?

 

[Moridin]

You could take a look at this . Though, if you're completely new to hashtables it might take a little while to get the hang of it.

Or base the summon ability on an ability that allows only one summon at a time, such as Feral Spirit.

I was thinking of that too, but you need a target point for healing wards. Most summon abilities generally just summon it infront of the casting unit.

 

[popo80000]

You can create a trigger that will pick every unit on the map.
Whenever you cast the summon ability, you will have a unit group that will pick all the summoned unit type owned by the owner of casting unit. Then you count how many summoned unit you have and how many witch doctor you have in the map. If both are the same or the summoned unit is greater than it, remove the summoned unit from the map.

The ablitty I made requires targeting a point. Hashtables are probally the only way to do it. I'm going to start learning how to use them, it just sucks because the computer I have in my room that I usually use for my map editing isn't fully updated, so if I add in hashtables I can't edit the map on that computer >.<. Oh well, thats just me whining.

I'm working on making Warcraft 3 the Board Game, thus I need the ablitty to be target-point.

this can help, i think

Quick Question though. Would that work for Setharoth114 ? I might be wrong, because I only glanced at your link, but it seemed like it was meant for summoning abilities like water elementals?
Also, I can't read/understand the code...so I have to ask you this .

@Moridin

This is a template

based on this spell, you create your own with your configurations

or... you can just use dire wolf (or something like that [ability of orc with chain lightning]) ability, because when you resummon, the old one die
